Bischof + Klein SE & Co. KG

The newly designed "Twister Plus" wicketed bag for tissue products necessitates around seven percent less material than conventional wicketed bags and requires significantly less effort for manufacturing. This involves reverse-printed hygiene packaging with a handle and easy opening function.

In close co-operation with a customer, the packaging and film specialist developed a new design for this converted packaging. The PE film for the bag can now be selected 10 µm thinner, for example. No additional label is required for the handle area. Thanks to the switch from first printing to reverse printing, an entire operation step is omitted. The quality of the printed image is improved at the same time.

Based on an order volume of 10 million units per year, the new wicketed bag enables over 14 tonnes of material – primarily polyethylene, but also lacquer – to be saved.

The AluFlex® product range is particularly suitable for moisture-sensitive products and additionally acts as a barrier for oxygen, light and odours. The PE/aluminium laminate is individually adapted to the customer's requirements in terms of its format and printing. Bischof + Klein offers AluFlex® as material on reels or an individual sack solution.

Bischof + Klein has achieved a quantum leap in terms of material efficiency with its new Value Pack. The large-format PE wicketed bag with handle is suitable for packaging large quantities of hygiene products such as paper tissues or toilet paper as used in hospitals or industrial enterprises, etc. The film has a wall thickness of 60 µm. Its maximum filled weight is 7.5 kilogrammes.

Cardboard packaging for a filled weight of approx. seven kilogrammes weighs around 600 grammes. A comparable PE wicketed bag only weighs 81 grammes. This also equates to lower transportation costs. This effect is enhanced due, for example, to the fact that the capacity of a Value Pack for paper tissues is around 15 percent higher. Easier handling thanks to the carrying handle offers an additional advantage.

The SmartFlex® 20 µm stretch hood film enables significant material savings. With this high-performance and super thin film, Bischof + Klein intends to conquer the market for securing lightweight, mixed products on pallets.

Conventional stretch hood films have a standard thickness of approx. 100 µm and are therefore economically unattractive for securing goods on pallets in certain market segments. With a significantly reduced wall thickness of 20 µm, SmartFlex® radically shifts the cost effectiveness calculation in the favour of stretch hood films and enables material savings of up to 39 percent in comparison with stretch wrapping films. The fundamentally higher performance of stretch hood film lines in comparison with stretch wrapping lines is further increased by SmartFlex® 20 µm, as the number of reel changes is reduced. Loads can be secured on 2,500 pallets with one reel.

In contrast to stretch wrapping technology, loads secured on pallets using hoods are per se protected on all sides and at the top from dust and moisture. The risk of theft is also successfully averted. Tampering with the film hood is immediately noticed.

The new stand up pouch for SONAX window cleaning solution can be recognised from afar thanks to its round form. Packaging specialist Bischof + Klein has developed unmistakable, flexible packaging in co-operation with its customer, SONAX, and packaging agency Berndt + Partner.

It is similar to the SONAX canister, which is also round, but offers the typical advantages of a stand up pouch: it saves space and material, and has little impact on disposal. One additional advantage in its handling is the small spout, which enables the solution to be poured precisely into even small openings without spluttering. The pouch simply contracts on pouring out. Since air does not have to be routed into the packaging at the same time to equalise the vacuum, the pouches' spout can be designed considerably smaller.

The stand up pouch for SONAX window cleaning solution is printed with seven colours and is equipped with a subdivided three-finger handle for easy carrying and pouring. It is stable and very well received at the point of sale.

With individual contours and formats between 50 ml and 10 litres, the stand up pouches from B+K offer high innovation potential. Another example is the stand up pouch in the form of a "Guglhupf" cake which Bischof + Klein has developed in close co-operation with a customer and a machine manufacturer. Thanks to the special material combination, the bag can be heated in a water bath or microwave oven along with its contents. The liquid frosting can then be distributed over the cake using the spout.

Bischof + Klein recommends the stand up pouch as an inexpensive and sustainable alternative to hard packaging with significant advantages, particularly as regards storage and transportation. Depending on customer requirements, various film combinations are used. Customers can choose from special shapes with various carrying handles, special pouch contours, resealable closures (zippers) or spouts.

The substrate films can be printed with up to ten colours via reverse or frontal printing using the flexographic and the gravure printing methods. The stand up pouch can be designed for sterilisation applications if required. It is suitable as packaging for detergents and cleaning materials, liquid soaps, foodstuffs, window cleaning solutions, lubricating oils, technical fluids or highly concentrated disinfectants.
